With the global shift from traditional advertising to digital marketing, the online world became the hot spot for advertisers worldwide. But considering how quickly the digital world evolves, it shouldn’t be surprising that the online advertising practices changed as quickly. Several years ago, most advertisers relied on display advertising and had to reach out to websites directly to purchase their ad inventory. But that quickly changed as various intermediary services popped up in the form of supply-side platforms.
These platforms appeared as an answer to a growing problem in the industry. As the online realm grew and more large publishers came to prominence, fill rates became an issue. Since publishers needed to find a simple and reliable way to sell their remaining ad inventory, supply-side platforms (SSPs) came into play as the optimal solution.
These platforms let publishers sell their ad inventory to some of the biggest names in the industry. Also, they optimize their yield by connecting them with both demand-side platforms (DSPs) and ad exchanges.
But SSPs became indispensable only once real-time bidding (RTB) became the next big thing in the online advertising world. The reason is that these platforms serve as intermediaries between advertisers and publishers (an auction house of sorts). Nowadays, there is no large online publisher out there who doesn’t utilize the benefits of supply-side platforms.
Just like with anything else in the programmatic advertising world, though, learning the ropes of SSPs and the benefits they provide to publishers is no easy feat. That is why we decided to write this in-depth guide to help you grasp the basics behind supply-side platforms and hopefully help you select the best one for your business.
We know that there’s a lot to digest, so we’ll start from the basics.
A supply-side platform (SSP) is a platform that helps publishers organize, sell, and optimize the distribution of their available ad inventory. These platforms allow publishers to monetize their sites and mobile apps in the most cost-efficient way possible using display, video, or native ads.
Supply-side platforms most often work on an automated auction-based model, where advertisers bid on the publishers’ ad inventory. That allows website owners to optimize their ad yield as they can choose to sell their inventory to the highest bidder. In other words, publishers get to sell their inventory to the best ad networks.
SSPs mediate the real-time bidding process by connecting publishers’ inventories to several ad exchanges and demand-side platforms. That helps them maximize their ad revenue because the more potential buyers publishers have access to, the better their odds of receiving higher CPM rates.

As we’ve mentioned above, SSPs are pivotal to real-time bidding transactions as they are “the auction houses” of online advertising. So what is their primary role, and what advantages do they bring to the table?
Supply-side platforms connect to data management platforms (DMPs), ad exchanges, ad networks, and demand-side platforms and streamline the technical side of the programmatic advertising process.
On top of handling all the necessary processes, using them benefits publishers in many ways:
As you can see, supply-side platforms bring a lot to the table. That is why they’ve become an essential component of many publishers’ programmatic advertising efforts. In fact, you’d be hard-pressed to find a prominent publisher that isn’t taking advantage of them nowadays.
As we’ve learned by now, a supply-side platform’s primary purpose is to sell publishers’ ad inventories to ad networks, directly to DSPs, or via real-time bidding. SSPs collaborate with DSPs to evaluate advertisers, track available ad inventory, set a bidding range, and filter any bids that don’t meet the publisher’s criteria. All of that happens in several micro-transactions across the ad supply chain and follows these steps:
Note: The SSP will insert a pixel code on the publisher’s web page to track visitor behavior. That will allow publishers to later request detailed reports from the platform to track and reevaluate their advertising strategy.
A question most of you probably have by now is: “What’s the difference between SSP and DSP?” We understand why you’d wonder that since these two services are pretty similar. However, there are some crucial distinctions between them.
A supply-side platform in its core is a platform publishers use to have an easier time communicating with various ad exchanges. It helps publishers handle the complicated process of selling and managing their ad inventory.
A demand-side platform provides an intuitive interface that advertisers use to manage buying ad inventory through multiple ad exchanges. However, a DSP has to connect to an SSP to enable bidding on publishers’ ad inventory.
As you can see, SSPs and DSPs have a similar role in the programmatic ecosystem, but they represent entirely different parts of it. SSPs are tools that publishers use to distribute their ad inventory, while DSPs operate on the advertisers’ ends. In other words, SSPs deal with selling ad inventory, while DSPs are in charge of buying it. That’s the gist of it!
